DIE-STOCK AND TAP-WRENCH.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed November 1X0, 1914. Serial No. 371,333.

T0 all whom it may concern:

Be it known' that I, EDWIN G. REID, a citizen of the United States, residing at Osage City, in the county of Osage and State of Kansas, have invented a new and useful Die-Stock and Tap-VVrench, of which p the following is a specification.

This invention has reference to die stocks and tap wrenches, and its object is to provide a convenient structure combining a, suitable number of various sizes of dies with corresponding taps, whereby the dies are all constantly in position for use and the taps are readily accessible.

In accordance with the present invention there is provided a body member of general polygonal form carrying peripherally an appropriate number of dies of different sizes, while extending centrally or axially through the polygonal body is the body portion of a tap wrench provided with means for the attachment of manipulating handles, the said body of the wrench andthe handles constituting the handle portion and support for the die holder. TheV handles are made hollow so as to `form receptacles for the taps, and the parts may be so proportioned that the handles will carry as many taps of i different sizes as there are dies` in the peripheral .portion of the body of the die holder. By this means the entire supply of dies which may include a suitable number of dies for all ordinary work, is always in position for use, while the taps are always accessible and the structure is simplified by the provision of a single pair of handholds or grips for both the die holder and the tap wrench.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification. with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings Figure 1 is an elevation of the structure when the parts are assembled for threading rods or pipes. 2 is an elevation partly in section showing` the tap wrench part of the structure removed plied thereto. Fig. 3 is a central longitudinal section of the structure of Fig. l with some parts in elevation. Fig. 4 is an end V1ew of the structure shown in Figs. 1 and 3.

Referring to the drawings, there is shown a generally polygonal block 1. Usually this block is made hexagonal and in the central portion of each plane face of the peripheral part of the block there is formed a radial soc'ket'2 openingthrough a central hole 3 1n its inner wall into a passage Il extending transversely of the block` parallel with the axis of the block. Since there are six sockets 2in the particular form shown there are six passages 4 arranged in circular series about a rectangular axial passage 5 through the.

to the axes of the passages 4. The passage 5 is shown as of elongated rectangular crosssection and fitted to this passage is a block 6 constituting the body portion of the tap wrench. For the reception of the taps indicated at 7 the block 6 is formed with one or moresuitably shaped passages 8, three of different sizes being shown in the draw ings, but this is to he taken as indicative of any suitable arrangement for holding the taps. Each socket 2 is designed to receive a die 9 of any suitable type and since the structure lis designed to produce threading of different sizes, each die 9 may differ from the others as to size or number of threads or both.

The body block G of the tap wrench terminates at the ends in threaded nipples 10 each designed to receive a respective tubular elongated handle ll closed at one end and suitably threaded at the other to receive the respective nipple 10, each handle there terminating in an exterior flange 1Q designed to abut against the corresponding end face of the die block l, so that when the handles are screwed upon the nipples 10 the die block lis firmly connectedlto the handles. Since it is customary to roughen the handles of die stocks and tap wrenches. the handles 1l may be similarly roughened by milling or otherwise to insure a lirin grip of the hands of the user thereupon.

It it be desired to thread a.rod or pipe the die stock consisting of the block l with the handles ll attached through the tap soY wrenchbody block 6 is always ready for use, no matter what size of die within the range of sizes provided is needed. The one structure without change or adjustment has all the different sizes needed always accessible, and no change or other manipulation is necessary. If it be desired tc use the structure for tapping threads, then the handles are removed from the nipples l0 or if need beonly one handle is removed therefrom and the block 6 is drawn out from its seat in the block 1, after'which the removed handle is reapplied to the block 6, the desired tap having been first chosen from those stored within the removed handle. Of course, care must be' taken toy remove that handle containing the desired tap, so that it will be unnecessary to unscrevv the other handle. The other taps not needed, if they have been removed from the handle, are returned thereto and the handleis reapplied to the block 6. Then by inserting the chosen tap in the proper hole 8 in the block`6 it becomes an easy matter to tap the threads into the pipe, nut or other place where' it is desired to produce the threads.

In using the dies the chips or shavings produced readily find theirway through the holesl 3 into the passages 4 and freely fall from the latter', so that there is no liability of choking up the dies with the removed chips of metal.

While the block 1 has been described as polygonal in outline, it Will be understood having a peripheral series of sockets for rethat it' may be otherwise shaped, although the polygonal form has certain advantages.

What is claimed is 1. A diefstock and tap wrench comprising a tap Wrench body with removable handle members at the ends, and a die block ceiving dies, and an axial passage shaped in conformity with the body of the tap wrench, said die block being engaged by the corresponding ends of the handles of the removable tap wrench when the tap wrench body and handles are applied to the die receiving block.

2. A die stock and tap wrench comprising a polygonal block with radial seats in its peripheral surface and dies seated therein, a

tap wrench body block in transverse relation to the die block, and handles applied to the ends of the tap wrench body in engagement with the die block and constituting the manipulating handles for said die block.

3. A die stock and tap wrench comprising a die block of polygonal outline with an axial passage and a circular series of other passages between the axial passage and the periphery of the block, said block having radial seats in its plane peripheral surface with holes connecting the seats with the respective ones of the second-named passages, dies adapted to the seats, a tap wrench body adapted to the axial passage through the die block and providedvwith threaded nipples at the ends, and handles applied to the nipples in engaging relation to the corresponding faces of the die block. i

4. A combined die stock and tap wrench comprising a die block with a central pas- 'sage therethrough and a peripheral series of receptacles for dies, and a tap Wrench having a body portion fitting the central passage through the die block and provided with handles at its ends constituting handles for the die block as well as for the tap Wrench.

5. A combined die stock and tap wrench comprising a tap wrench body having oppositely directed removable alined handles, and a die block centrally traversed by the body of the tap wrench and secured thereon by the handles, said die block being provided with a peripherally located series of dies.

6. The combination with a. tap wrench having removable handle portions, of a die stock in the form of a polygonal block with a peripheral series of dies, and a central passage adapted to lodge the body of the tap Wrench with the removable handles in clamping relation to the corresponding faces of the die block.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
